PENCIL SHARPENER.

Application filed October 17, 1922.

To all whom t may concern.'

Be it known that I, SYLvns'rnR K. MATH` nws, a citizen of the UnitedStates, and a resident of Albany, in the county of Albany and State ofNew York, have invented a new and Improved Pencil Sharpener, of

which the following is a full, clear, and eX- act description.

This invention relates to sharpening devices and has particularreference to a pencil Sharpener. y

An object of the invention is to provide a is sharpened by rotary andoscillatory movements of the pencil with respect to the cutting blades.

Another object is to facilitate the sharpening of the pencil byproviding a container or receptacle into which the shavings from thepencil are directed as the same are out from the pencil.

The above and other more clearly from the scription, when taken inconnection with the accompanying drawing, which illus-l trates apreferred embodiment of the inventive idea.

In 4the drawing` Figure 1 is a top plan view of the pencil Sharpenerconstructed in accordance with the invention p Figure 2 is a verticalsectional view on the line 2-2 0f Figure 1;`y

Figure 3 is a bottom plan view of the device;

Figure 4 is a section on the line 4-4 of Figure 5 showing a pencil inposition to be sharpened and illustrating' the Sharpener detached fromthe receptacle; and

Figure 5 is a side elevation of the sharpener detached from lthereceptacle so that' the same may be carried about the person.

The device consists of a body portion 6 of any desired configuration,having a bottom section 7 hingedly'connected to the body, as at 8 andprovided with a spring latch 9 engageable objects will appear followingdetail deof the pencil SharpenerI wherein the pencil' y'ting blades 17 ywhich includes with the bottoml edge ofl the body to maintain thelbottom section in 'closed position, said latch being adapted tovdescription, The top of the containend. thereof Serial No. 595,197.

er or receptacle 6 is cally arrangedbearing 10 in which a post orstandard 11 is adapted to be mounted and secured in position by means ofthe wing nut 12 which may be reached by moving the bottom section 7 toan open position.V The `upper end of the post or standard 11 whichextends beyond the lbearing 10 has secured thereto a sleeve 13,preferably arranged in an inclined position with respectto thekhorizontal and adapted to receive therein the'handle 14 of the Sharpenerproper. The inner end of the handle 14 is provided with a pair of spacedlugs 15 through which a `pivot pin lextends transversely with respect tothe handle and to which ad- ]acent ends of the cutting blades 17 aresecured. At a point intermediate the ends of the cutting blades 17 thesame are bent so that the free ends of said blades converge, as bestillustrated in Figure 1, and' the lower cutting edges 18 of the bladesare rounded and tapered toward the free ends thereof.

Also carried by the pivot pin 16 and positioned exteriorly of the lugs15 and cutis an oscillatory member, generally indicated by the numeral19 and oppositely disposed guards orv flanges 20, whichconverge'downwardly, as indicated in Figures 1 and 4;, and which havetheir lower edges 21 curved to substantially the contour of the` cuttingblades provided with aA vertitransversely of the pivot pin 16 so thatwhen the pencil 23 is inserted into the sleeve or holder the same willextend longitudinallyT of the cutting blades 17 and the oscillatormember 19 `and the sleeve is so disposed that the pencil will bearranged in ae plane between said cuttingblades. The ends of the guards2O remote from the pivot 16' areconnected by a transverse stop 24against which the end of the' pencilto be sharpened engages so as t'oproperly position said end with respect to the cut-ting blades.

When the pencil is in position the outer @grasped and thc'member 19 isswung about fthe pivot z16 to engage the end ot the pencil to besharpened with the cutting edges 1S ot the blades 17 and due to their'converging relation, it will be obvious that Said blades will cut intothe end of the pencil each time the same iS brought into contact withsaid cutting edges. After each cutting operation -the member 19 is movedabout its pivot in an opposite-direction and the pencil 23 iS given arslight rotation in the vholder 22 so 'that the next cutting operationwill Vsever a ditferent portion of the end ot the pencil. By repeatingthis operation it will be 'obvious that. the pencil may be given an evenand well defined point, after which the same may be withdrawn Jfrom `theholder or sleeve Q2.

In order that the shavings from the pencil may be accumulated in thereceptacle 6 'fand thus facilitate the sharpening ol lthe encil, thereceptacle or container@ is provided at a .point oppositethe latch 9with an opening 25 for receiving the lower end ot a chute 2G, whichentends outwardly vand upwardly from the receptacle. The Side members 2Tot theichute 26 are disposed on either side ot' the cutting blade 17 andthe guards '2O ot the oscillatory member 19 andare Widened at theirupper -ends to substantially enclose said parts whereby the Shavingstrom the pencil will be directed by the Side members into the bottom ofthe chute. 26 and trom thence in the receptacle G. The upper ends ot theside members ZT are provided with outwardly flared flanges 28 Awhichalso aid in directing vthe shavings into the chute 26.

Vlt will be obvious trom they oregoing description that should it bedesi-red to use the Sharpener including'the cutting blade 1T and theoscillatory member 19 without employing the 'receptacle 6 and chute 26,said sharpener may be detached from the receptacle by removing the wingnut 152 and then extracting the post 1l from the bearing l0, after whichthe handle le may be withdrawn from the sleeve 13. The operation otsharpening the pencil in this instance is practically the ysame @thatpreviously described er:- cept that instead of having the handle 1lrigidly connected to the receptacle 6 the same may be grasped with onehand and the pencil with the other hand`r whereupon the cutting bladesand oscillatory membermay be moved about the pivot 16 relative to eachother to secure the cutting action upon the end of the pencil positionedbetween the cutting blades and guards 20.

`What is claimed is:

1, ln a pencil Sharpener, converging toward adjacent ends thereof, anoscillatory member having pivotal connection Awith said blades at theother ends thereol, including guards extending eatericutting bladesltion for properly holder carpositioned in a orly olf said blades,andapencil ried by said member and plane between said blades.

2. .ln a pencil Sharpener, cutting blades converging toward adjacentends thereof, an oscillatory member having pivotal. connection with saidblades at the other ends thereotand including guards extendingexteriorly of said blades, a pencil holder carried by said member andpositioned in 'a plane between said blades, and a stop carried by saidmember remote 'from its pivotal connecpositioning' a pencil in saidholder with respect to said blades.

3. ln a lpencil Sharpener, a handle, cutting blades extendinglongitudinally from one end of said handle, a member having a portionpivotally connected to said end of the Vhandle and between said bladesand including a pencil holder arrangedon one slde of VSaid pivot andpositioned with respect to said blades whereby a 4pencil in ythe holderwill vhave a portion disposed between said blades, and guards alsoforming a part of said member arranged on the opposite side ot vSaidpivot and cooperating with said blades.

4f. ln a pencil Sharpener, a handle, cutting blades extendinglongitudinally end of said handle, a member having a portion pivotallyconnected to Said end of the 'handle and vbetween said blades andincluding pencil holder arranged on one side of Said pivot andpositioned with respect to said blades whereby a pencil in the holderwill have a portion disposed between Said blades, guards also 'forming a.part of said member arranged on the opposite'side of said pivot. andcooperating with said blades, and a stop connecting Said guards at theends thereof remote from said :pencil vholder and engageable by a pencilin said holder to 'properly position the pencil with respect to saidcutting blades.
